Consider shingles?: The earliest symptom of 'shingles' or reactivation of the varicella zoster virus (previously caused chickenpox) ---is severe pain along a nerve path (dermatome) before the typical rash is apparent. The shingles can affect a nerve path stretching from one side of the chest wall through the armpit and back to shoulder blade. But, there are many other causes of chest/shoulder pain -see a doctor soon!

Chest pain: It could be tmany things, but the presence of itching makes me think of shingles.
